Ok thanks to your help i solved all my problems everything works. I now have a much better understanding of this sanguino!
The bug of the heated bed sensor that didn't work regardless of the fact that both the pin and the sensor worked was simply because i disactivated the heated bed in marlin...
I have one last wonder: on the sevenswitch i used IRLB8743 just like on the sanguino.
When i run the sevenswitch with a small heatsink the MOSFET goes quickly above 120° ( i stoped at that point) so i would probably burn if i use it as is.
The seven MOSFET of the sanguino is the same without heatsink and it used to work fine.
Is it a quality diference between the 2 components ? Logically this mean that mine has a higher R, am i wrong here?
I am thinking of unsoldering the useless MOSFET of my sanguino and use it. Or use a wire between D12 and the gate of this old mosfet and use my actual sevenswitch for fan control with another Digital pin....
